Just be careful that you might run out of desire or interest in it, if it has lots to be done. You don't want that happening, if you can make a lower offer and stick to it, you always will have to come up with $$ once you own it, and a lower purchase price is incentive to put more effort into the truck as you go. So many guys lose interest ......then there they sit.
A more complete truck, original, is so much better to begin with I have found.
